Abstract

The invention discloses a preparation method of a modified glass fiber, and relates to the technical field of high performance fibers. The preparation method comprises following steps: (1) adding glass fibers in a rare earth solution, and processing glass fibers in an ultrasonic field; (2) blending the glass fibers with nano diatomite to modify the glass fibers; and (3) adding the glass fibers into a coupling agent solution so as to process the glass fibers. According to the preparation method, the glass fibers are modified, and the toughness, surface wear resistance, and surface compatibilityof glass fibers are effectively enhanced.

Description

technical field [0001] The invention belongs to the technical field of high-performance fibers, and in particular relates to a method for preparing modified glass fibers. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds of it. It has good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. Glass fiber is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns. All are composed of hundreds or even thousands of monofilaments. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields. However, due to the poor toughness and wear resistance of glass fiber, its popularization is limited. Contents of the ...
